It's roughly 48 x 12 in its standard dimensions, which is pretty narrow especially for a Syrian!

I would be hesitant to even house a dwarf hamster in it as well, but as a transitional smaller cage it could work nicely or even a potential quarantine cage if you ever needed one. Another idea for using it to not completely waste money would be using it as a play cage, mostly for the dwarf species rather than Syrians(but it could be useful during cage cleanings of a significantly larger cage for Syrians).
